Title:
POLYMER ELECTROLYTE FUEL CELL AND ITS USAGE
Document Type and Number:
WIPO Patent Application WO/2000/074165
Kind Code:
A1
Abstract:
A unit cell includes a pair of electrodes that sandwich polymer electrolyte film, and conductive separators that sandwich the electrodes, each separator having a gas supply channel in at least one side. A plurality of such unit cells are laminated with retainers and compressed into a stack to form a polymer electrolyte fuel cell in which the retainers provide gaps between unit cells. If any unit cell in a stack is found to be defective, it can be easily removed from the stack.
